Model 6036 is a four-channel, programmable charge amplifier, filter and digitizer with a second input for piezoelectric sensors with integrated electronics (IEPE). The high-performance charge amplifier can be used to measure dynamic acceleration, pressure, force and strain from piezoelectric transducers. Two charge-to-voltage input ranges optimize performance according to transducer sensitivity. A programmable time constant enables it to make quasi-static measurements. The charge amplifier has 3X overhead preventing its overload by signals in excess of full scale. A software ?overload? flag informs the operator if the input signal exceeds a selected threshold. A reset switch is provided to discharge the accumulated charge when using long time constants.
